Bilayer crystals of trapped ions for quantum information processing

March 25, 2024
Author(s)
Samarth Hawalder, Prakriti Shahi, Allison Carter, Ana Maria Rey, John J. Bollinger, Athreya Shankar
Trapped ion systems are a leading platform for quantum information processing, but they are currently limited to 1D and 2D arrays, which imposes restrictions on both their scalability and their range of applications. Here, we propose a path to overcome

Legacy of Charlotte Moore Sitterly in the Internet Age

March 19, 2024
Author(s)
Alexander Kramida
Most (yet not all) results of atomic physics research of Charlotte Moore Sitterly (CMS), which was closely connected to astrophysics, are now incorporated in online databases, one of which is the Atomic Spectra Database of the National Institute of

Simulating Meson Scattering on Spin Quantum Simulators

March 14, 2024
Author(s)
Elizabeth Bennewitz, Brayden Ware, Alexander Schuckert, Alessio Lerose, Federica Surace, Ron Belyansky, William Morong, De Luo, Arinjoy De, Kate Collins, Or Katz, Christopher Monroe, Zohreh Davoudi, Alexey Gorshkov

Photonic bandgap microcombs at 1064 nm

February 27, 2024
Author(s)
Gregory Spektor, Jizhao Zang, Atasi Dan, Travis Briles, Grant Brodnik, Haixin Liu, Jennifer Black, David Carlson, Scott Papp
Microresonator frequency combs and their design versatility have revolutionized research areas from data communication to exoplanet searches. While microcombs in the 1550 nm band are well documented, there is interest in using microcombs in other bands

Zeeman-resolved Autler-Townes splitting in Rydberg atoms with a tunable RF resonance and a single transition dipole moment

February 21, 2024
Author(s)
Noah Schlossberger, Drew Rotunno, Aly Artusio-Glimpse, Nik Prajapati, Samuel Berweger, Dangka Shylla, Matt Simons, Christopher L. Holloway
Applying a magnetic field as a method for tuning the frequency of Autler-Townes splitting for Rydberg electrometry has recently been demonstrated. In this Letter, we provide a theoretical understanding of Rydberg electromechanically-induced-transparency

Optical frequency division & pulse synchronization using a photonic-crystal microcomb injected chip-scale mode-locked laser

February 15, 2024
Author(s)
Chinmay Shirpurkar, Jizhao Zang, Ricardo Bustos-Ramirez, David Carlson, Travis Briles, Lawrence R. Trask, Srinivas V. Pericherla, Di Huang, Ashish Bhardwaj, Gloria E. Hoefler, Scott Papp, Peter J. Delfyett
A mode-locked laser photonic integrated circuit with a repetition rate of 10 GHz is optically synchronized to a tantalabased photonic crystal resonator comb with a repetition rate of 200 GHz. The synchronization is achieved through regenerative harmonic

Advancing Measurement Science for Microelectronics: CHIPS R&D Metrology Program

February 13, 2024
Author(s)
Marla L. Dowell, Hannah Brown, Gretchen Greene, Paul D. Hale, Brian Hoskins, Sarah Hughes, Bob R. Keller, R Joseph Kline, June W. Lau, Jeff Shainline
The CHIPS and Science Act of 2022 called for NIST to "carry out a microelectronics research program to enable advances and breakthroughs....that will accelerate the underlying R&D for metrology of next-generation microelectronics and ensure the

Emission Ghost Imaging: reconstruction with data augmentation

February 1, 2024
Author(s)
Kevin J. Coakley, Heather H. Chen-Mayer, Bruce D. Ravel, Daniel Josell, Nikolai Klimov, Sarah Robinson, Daniel S. Hussey
Ghost Imaging enables 2D reconstruction of an object even though particles transmitted or emitted by the object of interest are detected with a single pixel detector without spatial resolution. This is possible because the incident beam is spatially

Laser-power consumption of soliton formation in a bidirectional Kerr resonator

January 30, 2024
Author(s)
Jizhao Zang, Su-Peng Yu, Haixin Liu, Yan Jin, Travis Briles, David Carlson, Scott Papp
Laser sources power extreme data transmission as well as computing acceleration, access to ultrahigh-speed signaling, and sensing for chemicals, distance, and pattern recognition. The ever-growing scale of these applications drives innovation in multi

Intra-grain local luminescence properties of CdSe0.1Te0.9 Thin Films

December 25, 2023
Author(s)
Ganga Neupane, Behrang Hamadani, David Albin, Joel Duenow, Matthew Reese, Susanna Thon
We report on the local photoluminescence properties of grains and grain boundaries of CdSe0.1Te0.9 thin film deposited by the colossal grain growth method using a wide-field hyperspectral imaging technique. We observed significant variations in the

Visualizing the merger of tunably coupled graphene quantum dots

December 6, 2023
Author(s)
Daniel Walkup, Fereshte Ghahari, Steven R. Blankenship, Kenji Watanabe, Takashi Taniguchi, Nikolai Zhitenev, Joseph A. Stroscio
Coupled quantum dots have been realized in a wide variety of physical systems and have attracted interest for many different applications. Here, we examine novel graphene quantum dots in backgated devices on hBN, and visualize their merger using scanning

Bipartite time-energy uncertainty relation for quantum metrology with noise

December 5, 2023
Author(s)
Philippe Faist, Mischa Woods, Victor Albert, Joseph Renes, Jens Eisert, John Preskill
Noise in quantum metrology reduces the sensitivity to which one can determine an unknown parameter in the evolution of a quantum state, such as time. Here, we consider a system prepared in a pure state that evolves according to a given Hamiltonian. We
